Synopsis
========

Multiple vulnerabilities have been found in dhcpcd allowing remote
attackers to possibly execute arbitrary code or cause a Denial of
Service.

Background
==========

A fully featured, yet light weight RFC2131 compliant DHCP client

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-misc/dhcpcd              < 6.10.0                  >= 6.10.0

Description
===========

A heap overflow can be trigged via malformed DHCP responses in the
print_option (via dhcp_envoption1) due to incorrect option length
values.  These vulnerabilities could also allow remote attackers to
trigger an invalid read/crash via malformed DHCP responses.

Impact
======

Remote attackers could possibly execute arbitrary code with the
privileges of the process or cause Denial of Service.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All dhcpcd users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-misc/dhcpcd-6.10.0”
